August 4 marks the 100th anniversary of the birth of Swedish diplomat Raoul Wallenberg. As Sweden’s envoy in Budapest, Hungary, during World War II, Wallenberg issued passports and sheltered Jews in Swedish-controlled buildings, effectively saving tens of thousands from extermination by the Nazis.

In January 1945, Wallenberg was detained by Soviet officials and was never seen again. Various reports say he was killed in custody soon after or that the Soviet Union continued to hold him in prison for decades. His disappearance remains a mystery.

Wallenberg should be remembered for embodying humanitarian ideals of the highest level. At great risk to his own safety, Wallenberg demonstrated a remarkable courage in his selfless actions. His moral fiber was of the highest caliber.
